The Federal Motor Carrier Safety Administration (FMCSA) Drug & Alcohol Clearinghouse is a critical tool for the commercial transportation industry. It helps improve safety by tracking drug and alcohol violations for drivers with commercial driver’s licenses (CDLs) and commercial learner’s permits (CLPs). 

For employers regulated by the Federal Motor Carrier Safety Administration (FMCSA), a compliant random drug and alcohol testing program is a required part of operating a safety-sensitive workforce. The rules are clear in principle. Drivers must be randomly selected for testing each year at the rates set by FMCSA. In practice, employers often encounter challenges that can affect compliance if the program is not carefully managed.
